IMPROVEMENT IN COOKI NG-STOVES.

Specification forming part of Letters Patent No. 40,174, dated October 6, 1863.

To all whom it may concern.-

Be it known that I, T. S. LAMBERT, of Peekskill, Westchester county, New York State, have invented a new and Improved Cooking-Stove or Range; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters and figures marked thereon.

The nature of my invention consists in, first, constructing the grate-rest and grate in such a manner as to regulate the quantity of coal burned and the position where it shall burn most vividly; second, constructing the oven-slide with hooks, and the upper part of the oven-sides with slide'rests, so that meat or fowls may be hung while roasting and easily drawn out for examination or basting, and their relative position in the oven changed readily; third, constructing brackets to fit the upper back part of the stove so as to sustain a reservoir with dampers, when desirable, opening beneath it for" rapidly heating it; fourth, constructing jackets upon the bottom and sides in connection with a warmingcloset or reflecting oven at the back of the stove.

I take a stove or range, Letters Patent for which were issued to me on April 8, 1862. .To the under surface of the grate-rest A, upon one or both sides, I apply a slide or damper with scalloped (as at a, Figure 1) or straight edge, by means of a rivet, as at 1), moving in the slot 0, the direction of which is such that when the damper is drawn forward it is carried toward the grate, diminishing the surface above which the coal vividly burns, therefore preventing the coal from burning so intensely against the oven when the damper on that side is drawn, and, when both slides are drawn, causing the burning to be intense in a narrow space. To the under surface of the back part of the grate B, Fig. 1, in which the grate is inverted to show its lower surface, a slide is to be applied by the rivet e, or other device, working in the slot f, so that when the slide or damper d is drawn forward and to the side aof the grate it will underlie the spaces of the back part of the grate. By the action of the back-grate damper and the grate-rest dampers' combined with the draft dampers in the side and front of the ashpit, an improved control is had over the combustion of the coal.- On the upper part of the inner surface of the sides of the oven, and opposite to each other, slide-rests should be cast to receive the ordinary slide of an oven, the bars of which should receive several movable hooks. It will be convenient to have them in pairs of different lengths. A reservoir with a pipe extending through it is to be placed about the pipe-col lar. To sustain it in position a bracket, as seen at Fig. 3, may be hooked into orifices in the rim of the back part of the top of the stove, and rest by the leg u against the back plate of the stove and a ledge cast thereon, or inserted in a loop, as at t, Fig. 2, or the bracket may be continuous along the back of the stove, as shown by F F, Fig. 1, in which case slides can be placed over holes made in the upper part of the back plate of the stove-one being above the back of the fire-box and the other at a corresponding place beneath the other end of the boiler, asseen'at G G.

Thus with slight expense all this class of stoves can be prepared to receive brackets and a reservoir-boiler, when desirable, and the heat in its full intensity can be directed under the reservoir.

The length of the continuous bracket and the breadth of it must depend upon the size of the reservoir to rest upon it.

The jacket to be applied beneath the stove is to be open in front, but closed upon tle sides and at the back, and so constructed that the air which flows into it in front, will pass up the sides of the stove either through holes in the margin of the bottom K, Fig. l, or in a corrresponding manner. The jackets L L should reach from the top of the stove to the bottom, being sprunginto proper ledges or lugs to receive their edges, and should reach also from the front of the stove to the reflecting-oven or warming-closet, so that the hot air from the jacket below the bottom of the stove may be still more heated in the side jackets and pass on into the reflecting-oven. If the reflecting-oven does not extend the whole length of the back of the stove, but is restricted to the flue part, the side jacket should be carried round the back till it meets and opens into the reflecting-oven. The reflecting-oven should be from ten to fifteen inches wide, of the same height as the stove,

and if designed for baking or roasting should be of double thickness, with a single door, but lined. Its upper and lower angles should be removed and a curved form substituted, and its lining s.ould be creased at right angles to .permit the best of action.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The application of the slide A to the bottom of the grate-rest, substantially as set forth.

2. The application of the slide d to the half of the under surface of the grate, substantially as set forth.

3. The combination of the grate-rest slide and the grateslide at, substantially as set- :forth.

4. The combination of the hooksp, the slide as set forth.
